Another example is somebody getting eaten by a whale, then escaping through the blowhole. A whale's throat and blow hole are not connected, therefore escape is impossible.

Waaa?...Well, learn ya somethin' new...what flick did this happen in?

It happens mostly in either animated features or kid's films. I think the last time I remember something like that happened (to the best of my knowledge) was in Ice Age 4. Might seem silly to complain about an error in films like that, but I see plenty of serious films treat the humans only use 10% of their brains myth as fact so why not point out this flaw.

I like zoology (zoological gardens, natural history museums, etc) so this is the kind of things I notice.

In THE VALACHI PAPERS, there is a scene that is supposed to take place in the 1930s that involves a car driving through traffic. You can clearly see a car driving in the background that is a late 1960s or early 70s model car.

In the same movie, when Charles Bronson gets attacked in the prison shower, you can catch a glimpse of a bathing suit or pair of underpants he is wearing when he is supposed to be naked. And don't ask me why I was looking at Bronson's ass while I was watching this scene.

That's because Bronson has a nice ass. Not that I've ever seen him naked or anything like that. I just heard that from someone.
